Introducing Noxtee: the nighttime formula that helps you fall asleep without listening to the ringing, wake once instead of three times, and stop the 3am wind-up that makes it louder.
Sleep through it or your money back — 90 days
You are not imagining it. You did not fail to push hard enough.
The ringing is not made in your ears. It is made at one point in your brainstem, and it is running right now.
Every sound your ear picks up arrives here first.
This bundle sets how loud things need to be. Quiet room, it turns you up so you can hear a whisper. Truck goes past, it turns you down so the truck does not hurt.
It has been doing that for you since the day you were born.
Above 8,000 hertz you have lost a little hearing. Almost every woman our age has, and it can sit in the connection between ear and nerve, which leaves your thresholds looking perfect.
8,000 hertz is where a standard hearing test stops. So it never reaches the chart, you get told you are normal, and your file gets closed.
The bundle still notices. It is getting a weaker signal, so it turns itself up, and it overshoots. Turn a radio up with no station tuned in and you get a hiss. That hiss was always there. You only turned it up loud enough to hear. That is the sound seven doctors could not find.
These are the only cells in your body where three nerves land together: ear, jaw, neck. So the volume goes up on all three. That is why clenching changes the pitch. Your dentist checked the jaw wire, your ENT checked the ear wire, your physio checked the neck wire. Nobody checked the box.
It runs all day. Three things cover it while you are awake: the sound around you, whatever your mind is on, and the waking filter that throws away what does not matter.
At eleven the room goes quiet and you lose the first one. That is why you run a fan in January.
By three you lose the other two. Sleep pressure is spent, your stress hormone is climbing toward morning, and after years of this the alert part of your brain never switched off properly anyway.
So the ringing does not get louder at three in the morning. You get more awake.
And it does not settle on its own. Every night you lie there checking it, rating it against last night, you tell your brain the sound matters, and your brain turns up what matters. The listening is what feeds it.
Noxtee combines glycine at 3 grams — the amount used in the research, and the one ingredient nobody selling you a tinnitus pill has ever put in front of you at a real dose.
Standardized saffron extract, L-theanine, and magnesium bisglycinate — the form that actually gets in, not the oxide sitting in your drawer that did nothing. Timed to work in sequence, because they hand off to each other. One capsule pair, one time, nine at night.
And you don't need to sit through another specialist appointment, spend another four thousand on something you'll wear twice a month, or try another tinnitus formula with fourteen things on the label and none of them in there in an amount that does anything… to get your nights back.
Because Noxtee works on both halves of what's keeping you awake — the volume turned up at the source AND the three-in-the-morning wind-up that pulls your last cover off… so you can finally:

"Every week I see a patient with a clean audiogram and ringing that's very real. The hearing test looks at the cochlea — but the signal that becomes the ringing is turned up at the volume knob in the brainstem. That's not a place an audiogram can see. This formula starts there. That's what makes it different."
Board-Certified Neurologist • Central Auditory Pathway Focus
"Tinnitus is not always an ear problem. The sound can come from a real neurological junction in the brainstem, even when the ear and the audiogram look normal. That is why patients can hear it clearly while every ear test says nothing is wrong. The location is neurological, not aural."

A night guard can protect the teeth, but it cannot reach that junction. That is why two guards can fail while the ringing continues. The bite was never the whole story."

Everyone's different. But after 3,000+ women, we see a pattern.
The glycine moves heat out through your hands and feet, which is the signal your body actually uses to start the night. Most women notice the gap between lying down and falling asleep getting shorter. Not silence. Just less time standing in that doorway.
You wake once instead of three times. And the first time you wake at three, hear it, and go back to sleep without checking it — that's the week it usually happens. You won't notice it that night. You'll notice it in the morning, when you realise you didn't lie there rating it against the night before.
Same bedtime every night, without deciding to. You finish a book. You stay at the table. The ringing is still there if you go looking for it in the morning — but it isn't the loudest thing in the room anymore. Sleep is.
You stop checking it altogether. And when you stop listening for it, you stop feeding it — which is the whole thing seven specialists never told you. That's why 87% of women reorder.

"Eleven bottles in my nightstand and I fought the last company for eleven weeks over a refund. I ordered this expecting to throw it in the drawer with the rest. Week three I woke at three, heard it, and went back to sleep. I didn't check it. I didn't rate it against the night before. I just went back to sleep. That hadn't happened since 2016."
Glycine — 3,000mg. Three grams. Not three hundred milligrams — three thousand. This is the amount used in the sleep research, and it is the one ingredient nobody selling you a tinnitus pill has ever put in front of you at a real dose. It works by moving heat out through your hands and feet, which is the signal your body actually uses to start the night. It's the difference between being tired and being sleepy. This is Step 3, and it is the reason the bottle is the size it is.
L-Theanine — 200mg. This is Step 1. It lowers the alarm response, so when you do notice the sound, your whole body doesn't switch on behind it. You hear it, and nothing happens. Without this step, everything after it is working against a nervous system already braced.
Standardized Saffron Extract — 28mg. Step 2. Not saffron powder — a proper standardized extract, tested for its active compounds. Most of what's sold as saffron is an expensive spice. This one closes the door between lying there and being asleep. That door is the one you've been standing in.
Magnesium Bisglycinate — 200mg. Step 4, and the foundation underneath the other three. If you've taken magnesium before and it did nothing, you almost certainly took the oxide — the form that barely gets in. Bisglycinate is bound to glycine, which is how it actually crosses. It makes the whole system harder to wind up, so an ordinary three o'clock stir doesn't turn into an hour of listening.
Two capsules. At night. With a glass of water. No morning dose to remember. No powder to mix into a glass. Every ingredient is at the amount used in the research — which is why there are four of them and not fourteen. Blends that list fourteen ingredients have room for a pinch of each and a meaningful dose of none.
These ingredients work in order — first lowering the alarm, then closing the gap to sleep, then triggering the physical drop, then holding the system down through the night. That's why the other bottles failed. They handed you one step, at a fraction of the dose, with no order at all.
Everything your ear picks up arrives first at a small bundle of nerve cells at the base of your skull, about the size of a pea — the dorsal cochlear nucleus. Its one job is deciding how loud things need to be. Quiet room, it turns you up. Truck goes past, it turns you down.
Above 8,000 hertz — exactly where a standard hearing test stops — nearly every woman our age has lost a little hearing. It never shows on the chart. But that bundle notices the weaker signal, and does what a volume knob does when the signal gets weak: it turns itself up, and it turns itself up too far. Turned up that high, it starts hearing itself. That hiss is the ringing.
It doesn't turn itself back down on its own. And every night you lie there listening to it, checking it, rating it against last night, you're telling your brain that this sound matters — and your brain turns the volume up on things that matter. The listening is not a symptom of the problem. It's the engine.
Noxtee works in 2 phases:
Phase 1 (Nights 1–14): L-theanine and saffron lower the alarm and close the gap to sleep, while glycine triggers the physical temperature drop your body uses to start the night. Most women notice the time between lying down and falling asleep getting shorter first.
Phase 2 (Week 2 onwards): With the nights holding, magnesium bisglycinate keeps the system from re-winding at three in the morning. You wake once instead of three times. Then you wake, hear it, and go back to sleep without checking it. That's the night the engine stops being fed.
Most tinnitus supplements aim at the ear. The ear is where the signal weakened. The brainstem is where the volume was turned up. That's the difference.

This isn't another "proprietary blend" where fourteen ingredients hide behind one vague number. Every ingredient is dosed at the amount used in the clinical research — which is why there are four of them, and why the glycine is 3,000mg and not a sprinkle. You've bought enough bottles that didn't tell you what was in them.

I don't write reviews. Ever. But this deserves one. Nine years of ringing, five doctors, every test normal. Meanwhile I was running a fan in January so the room was never quiet. Three weeks on Noxtee and my husband said at breakfast on a Saturday "you didn't get up last night." I DO sleep different. Because I actually slept. And woke up without that first thought being is it louder today. I'm not saying it's a miracle. I'm saying it's the first thing that's actually DONE something in nine years.

THE FAN. That's it. That's the review. Slept with the window open and no white noise for the first time since 2019. 🙌

Tried Lipo-Flavonoid, Quietum Plus, magnesium, ginkgo, a $900 night guard and a $3,200 retraining program over 6 years. Nothing. This is the first thing that addresses WHY it's happening instead of telling me to mask it. 5 weeks in. Will update at 3 months.

The 3am checking stopped. Just stopped. I'd been rating it against the night before for six years and thought that was just my brain now. It wasn't. 🙏

Ringing for 11 years. Nothing else worked. This works. Sleeping through, head clearer, finished an actual book. Ordered 3 more bottles.

68 years old. Ringing since 2019. I have tried everything on Amazon. Every supplement. Every "tinnitus formula." Eleven bottles in my nightstand and about $1,400. My daughter found this and I almost didn't order it because I was so tired of being disappointed. Glad I did. I fell asleep without noticing I'd fallen asleep around night ten. Last week I woke at three, heard it, and went back to sleep without checking it. That might sound small but if you know you know.

Audiogram "perfect" according to my ENT. Meanwhile I couldn't follow a conversation at a restaurant without leaving the table. Three weeks on Noxtee and the nights started holding. First thing that's matched what I actually experience instead of what my chart says.

I read them the ingredients over the phone before I ordered — my pharmacist, not the internet. She went through all four with my HRT and my statin in front of her and said it was fine at those amounts. Then I told my doctor at my next appointment and he WROTE IT DOWN. That tells you everything.

Best impulse purchase of my life. Saw the ad at midnight. Couldn't sleep as usual. Ordered at 12:47am. Six weeks later I'm asleep by 10:30 without the TV on low. Never going back.

Bought this for my mom. Seven specialists over nine years and every one of them told her she was fine. She called me crying on week three saying somebody finally told her where it was coming from. I'm not crying you're crying 😭

Finally a tinnitus supplement that isn't 300mg of magnesium and a prayer. Look at the glycine — three grams. Six years of this and it's the first label that had a real dose of anything on it. Took about 3 weeks but once it kicked in… the difference is real. Still there if I go looking for it in the morning. Just isn't running my nights anymore.
It's a 2-phase nightly capsule routine designed to address the relay station behind your ear — the dorsal cochlear nucleus — the part of your auditory pathway the audiogram doesn't measure.
Phase 1: L-theanine and saffron extract calm the cortisol-axis stress that's been wearing the inhibitory brakes down all day.
Phase 2: 3,000mg glycine and magnesium bisglycinate refill the two natural brakes — magnesium and glycine — at research-strength doses.
Most "tinnitus" formulas (Lipo-Flavonoid, Quietum Plus, Tinnitus 911) target the cochlea or throw a kitchen-sink blend at the ear. The cochlea is the speaker. The relay is the amplifier. Most "calm" formulas only do trace amounts of step 2 ingredients — 100mg of glycine, 50mg of magnesium oxide. Noxtee does both phases, at the doses published research uses, in the right order. That's why patients who'd already tried everything saw something different on Noxtee.
90 nights to feel the night hold. If it doesn't, keep what's left — every cent back, no return shipping required.
Probably more than your GP has told you.
Here's the chain nobody connects. Every night the relay over-fires, your sympathetic nervous system stays in fight-or-flight while you're trying to sleep. Cortisol stays elevated. Your blood pressure does not dip the way it's supposed to during sleep — it stays elevated for eight straight hours, every night, for years. That is the load behind the cardiac events that show up in women in their 50s and 60s — events that should be happening twenty years later.
Sofi et al. 2014 meta-analysis: chronic insomnia is associated with roughly a 45% increase in cardiovascular mortality. The 2026 review in Nature Reviews Neurology confirmed the brake-failure mechanism behind it.
Noxtee does reload the two brakes that quiet the relay so your nervous system can downshift at night the way it's supposed to. The cardiovascular risk pathway runs through chronic broken sleep. That's where Noxtee starts.
If you don't feel the night hold within 90 nights, keep what's left and we refund every cent.
Yes. In fact, it's specifically for you.
The audiogram tests the cochlea — the speaker. The signal that becomes the ringing fires one stop upstream, at the dorsal cochlear nucleus — the amplifier. The audiogram cannot reach that relay. So your test was honest. It just wasn't looking where the ringing actually fires.
A "normal audiogram" is not a clean bill of health. It is the result that closed your ENT's file the moment the cochlea checked out — while the relay above it kept firing every night. The relay was never on the test.
If your audiogram came back normal, your ENT told you to "learn to live with it," and your nights are still wrecked — Noxtee was built specifically for you. 90 nights to feel the difference. Worsening-protected refund.
Fair question. You've probably already spent $300 to $1,500 on Lipo-Flavonoid bottles, Tinnitus 911, magnesium oxide pills, melatonin gummies, lavender oil, white noise machines, and a night guard. None of it touched what's actually firing.
Noxtee is the only nightly routine on the market dosed for the relay junction upstream of the cochlea. The doses aren't marketing — they're what the research uses:
3,000mg glycine. The Yamadera 2007 dose.
200mg magnesium bisglycinate. The bioavailable form that crosses the blood-brain barrier.
200mg L-theanine. The trial-grade dose.
28mg saffron extract. The mood and sleep-quality research dose.
90 nights to feel the night hold. Worsening-protected refund — if your nights feel worse, not better, contact support, keep what's left, every cent back. No return shipping. No chat queue. No questions.
The only risk is staying exactly where you are.
Because the relay junction isn't on their test, and the formulation isn't a prescription.
ENTs are trained to read cochleas. The dorsal cochlear nucleus sits in the brainstem — outside their imaging, outside their certification, outside the audiogram. When the test comes back clean, the case closes. That's not malpractice. That's the limit of the tool.
The 2026 Nature Reviews Neurology review on glycinergic and NMDA modulation at the dorsal cochlear nucleus is recent. Yamadera 2007 sat shelved for over fifteen years before the field caught up. The doses Noxtee uses are research-grade, not prescription-grade — your ENT is not licensed to prescribe a nightly routine. They are licensed to test the cochlea and refer.
The reason most patients hear about this from each other before they hear it from a specialist is that the gap between published neurology and ENT practice is roughly fifteen years. Noxtee is what closes that gap.
We get this question more than almost any other.
Lipo-Flavonoid is bioflavonoid-based. It targets vascular flow at the cochlea. It's been on the shelf since the 1960s and it does not touch the relay junction at the dorsal cochlear nucleus. If your audiogram came back normal, Lipo-Flavonoid was solving the wrong organ.
Quietum Plus is a proprietary blend. The label hides individual doses behind the "proprietary blend" label so you cannot see how much of anything is in it. You're paying for a marketing label, not a verifiable research dose. Real biology requires real doses you can read on the supplement panel.
Tinnitus 911 sells a vitamin and herb blend marketed primarily through aggressive paid placements. None of its ingredients are dosed for the relay junction. It relies heavily on bioflavonoids and surface-level vitamins — nothing that reaches the inhibitory brakes at the dorsal cochlear nucleus.
Noxtee uses 4 ingredients, all individually disclosed at research-grade doses, all targeting the actual junction where the ringing fires. No proprietary blend. No bioflavonoid theater. Real doses, the order they need to be taken, the form that reaches the brain.
90 nights to compare it side-by-side. If it doesn't outperform whatever you're taking now, keep what's left and we refund every cent.
Yes — and this is the single most common medication stack we see among Noxtee buyers.
Noxtee contains no synthetic compounds and no prescription-active ingredients. Just L-theanine, saffron extract, glycine, and magnesium bisglycinate. All four are widely tolerated alongside:
Statins (atorvastatin, rosuvastatin, simvastatin)
BP medications (lisinopril, losartan, amlodipine, metoprolol)
Blood thinners (apixaban, warfarin, clopidogrel)
SSRIs and anti-anxiety medications
Prescription sleep aids (zolpidem, eszopiclone)
Thyroid medications (separate by 4 hours)
Magnesium bisglycinate at 200mg is well below the threshold associated with any clinical interaction. Glycine at 3,000mg is the dose used in the Yamadera trial — published, peer-reviewed, well-tolerated.
If you are on a prescription, run the ingredient list past your prescribing doctor before you start. Email contact@noxtee.com and we'll send the full dose breakdown — print it, bring it to the appointment.
Yes — and it's the only dose with measurable sleep-quality data behind it.
Yamadera et al. 2007 measured sleep-quality changes at exactly 3 grams glycine, 30 to 60 minutes before bed. Lower doses (500mg, 1g) did not produce the same effect on subjective sleep quality or on polysomnographic measurements. The biology requires the dose.
Glycine itself is one of the most abundant inhibitory neurotransmitters in your nervous system. Your body produces it. You consume it from protein. A cup of bone broth contains roughly 3 to 4 grams. The dose is well within the natural range — it's just concentrated and timed for the window when your relay needs it most.
Most "calm" or "sleep" gummies use 100 to 500mg of glycine — a marketing gesture, not a therapeutic dose. Noxtee uses the trial dose. 3 grams. Every night. That's why the brake actually reloads.
That's the most common starting point we see. Most people who find Noxtee have already done:
The magnesium oxide. The Lipo-Flavonoid (sometimes for years). The Quietum Plus or Tinnitus 911. The melatonin gummies. The valerian root. The lavender essential oil on the pillow. The white noise app, then the fan, then the second white noise app to mask the first. The ashwagandha. The L-theanine on its own. The night guard. The four-figure ENT bills. The "have you tried meditation" from a well-meaning friend.
None of it worked because none of it reached the relay junction.
The cochlea was the wrong target. The ear muscle was the wrong target. The melatonin half-life was the wrong target. The relay junction at the dorsal cochlear nucleus — the place every signal from your ear, jaw, and neck has to pass through on its way to your brain — was the missing target every single one of those products skipped.
Noxtee starts where everything else stopped. 90 nights at the trial dose. Worsening-protected refund.
The wind-down change comes first. Most people notice the bedtime bracing — the 9:30 PM "what is the room going to sound like" anticipation — easing up by night 5 or 6.
The 3 AM wakeup pattern usually starts breaking around week 3. When you do wake up, the night doesn't restart from zero — you fall back asleep faster.
Mornings start feeling less like a verdict by week 5 or 6. The "how loud is it today" first thought fades.
The full pattern shift takes 90 nights — which is why the trial window is 90 nights, not 30. Some bodies respond faster, some slower. Magnesium and glycine reload over weeks, not hours. The relay has been running on empty for years. Reloading both brakes consistently takes the time it takes.
The 90-night worsening-protected guarantee covers you either way.
Every nervous system in human biology runs the dorsal cochlear nucleus on the same two inhibitory mechanisms — magnesium ion blockade at the NMDA receptor, and glycine inhibition at the receptor downstream. That's not a regional difference. Not a Hashimoto's-vs-non thing. Not a "my body is unique" thing. That's basic neurology, in every textbook.
Whether your gauntlet history has 2 specialists or 7 in it, whether you've worn a night guard for 6 months or 16 years, whether you have hearing aids or not — the relay still runs on those two brakes. Noxtee refills them.
If your nights feel worse, not better, after 90 nights — contact support, keep what's left, every cent back.
Yes. And this is one of the reasons Noxtee works for people who saw their dentist before they saw an audiologist.
The dorsal cochlear nucleus is where signals from your jaw, your neck, AND your auditory nerve all converge. Three nerves, one junction. Clenching feeds the same junction that's already over-firing from the auditory side.
A night guard protects your teeth from the grinding. It does not protect the relay from the signal. The signal still arrives. The brakes still get burned through. The 3 AM wakeup still happens.
Keep wearing the guard for your teeth. Take Noxtee for the relay the guard doesn't reach.
Noxtee is non-habit-forming. Contains no melatonin, no GABA agonists, no benzodiazepines, no kava, and no sedating antihistamines — none of the compounds that create dependency or downregulation.
Glycine, magnesium, L-theanine, and saffron are well-tolerated. Glycine in particular is one of your nervous system's own inhibitory neurotransmitters — your body makes it. Magnesium bisglycinate at 200mg is well below any threshold associated with side effects in published research. Most people experience no side effects at all.
No. The goal is to restore the routine, not create a dependency.
Many people take Noxtee nightly for 90 to 180 nights, find their pattern stabilizes, then either reduce to a few nights a week as needed or stop entirely. Some keep taking it nightly because the wind-down support is something they want every night.
Your body still produces glycine on its own. You still process magnesium from food. Noxtee is supporting those systems at the relay junction during the years they're depleted. Once the pattern shifts, your body keeps making and using both — the same way it always has.
Stop anytime. No tapering protocol. No withdrawal. No rebound.
No. The dorsal cochlear nucleus does not have an expiration date.
Your nervous system still uses the same two inhibitory mechanisms it used the night this started — whether that was 2014 or 1998. Magnesium ion blockade. Glycine inhibition. Both still work at the receptor level whether you're 35 or 75. The brakes can be refilled at year 1 or year 21.
Some of the strongest pattern shifts we see come from people who'd been "managing this" for 10, 15, 20 years and had stopped expecting anything to change. The biology doesn't care how long it's been. It cares whether the inputs are there.
If 90 nights at the trial dose don't shift your pattern — keep what's left, every cent back, no questions.
We know.
That might be the most honest sentence on this entire page. You've been let down by 4 specialists, every supplement on the shelf, two different night guards, and the audiogram that came back "normal" while your nights kept falling apart. Protecting yourself from another disappointment feels safer than trying.
We can't promise you a miracle. We can promise you this:
The mechanism is real. The doses are at research-grade strength. Yamadera 2007 measured the glycine effect at 3 grams. The 2026 Nature Reviews Neurology review confirmed the brake-failure pathway. The biology is universal — every nervous system runs on these two brakes.
90 nights to feel the night hold. Worsening-protected refund — if your nights feel worse, not better, keep what's left and we refund every cent. No return shipping required. No chat queue. No questions.
The only real risk is staying exactly where you are — for another year, another decade, another 3 AM wakeup that starts the night over.
The brakes can still be refilled. The relay can still quiet down. The version of you who fell asleep without thinking about it is closer than you think.
